3sge AE86 limp mode? Diagnostics?

Postby mk2glenn » Tue Sep 29, 2015 9:55 am

Friend of mine has an Altezza 3SGE in an AE86. Car runs and drives perfect but I think it's in limp mode as it's well down on power.

The only problem is theres no diagnostic socket wired in, is there any other way of running diagnostics on the ECU?

Flash codes, just find the relevant pins on the ecu and wire in a light?

I think W is pin 7 on the 22 pin plug, That'll go to one side of the the bulb, use a 5w. The other side will be a fused 12v power source.

Then earth TC, I think it's pin 24 on the 28 pin plug.

You should get fault codes then.

Pretty easy to read the fault codes.

This is on the NZ site:

I had success with the one under the dash and didn't try the other plug cos didnt need to :)
